Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements presented herein include 100 percent of our assets, liabilities, revenues, expenses and cash flows as well as all entities in which we have a controlling financial interest. In our opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All material intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect our financial position, results of operations and cash flows as prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Although we believe the disclosures made are adequate to prevent information presented from being misleading, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto as of and for the year ended December 31, 2020, included in our Annual Report on Form 10-K filed with the SEC on March 1, 2021. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and, accordingly, ultimate results could differ from those estimates. Interim results are not necessarily indicative of full year performance. Impact of the COVID-19 Pandemic The novel coronavirus (“COVID-19”) pandemic that started in early 2020 significantly negatively impacted the hospitality, travel and leisure industries due to various mandates and orders to close non-essential businesses, impose travel restrictions, require “stay-at-home” and/or self-quarantine, and require similar actions. Such restrictions and directives have resulted in cancellations and significant reductions in travel around the world and caused various other negative global economic conditions. In response to these events, we closed substantially all of our resorts and sales centers during early 2020, but began a phased reopening of resorts and resumption of our business activities during the second quarter 2020 under new operating guidelines and with enhanced safety measures as mandates and orders for business closures, quarantine and travel restrictions began to ease. With the anticipated continuation of the pandemic receding, as well as COVID-19 vaccinations becoming more widespread, such mandates and orders have continued to ease, resulting in consumer confidence increasing to resume normal activities, including travel and leisure, and more businesses to continue to resume operations. Accordingly, the positive trends in leisure travel and stays at our properties have continued. For example, as of March 31, 2021, we have approximately 80 percent of our resorts and nearly all of our sales centers open and currently operating, although many are operating in markets with various capacity constraints, social distancing requirements and other safety measures, which are impacting consumer demand for resorts in those markets. We plan to continue to reopen our resorts and resume our normal business as conditions permit, but there can be no assurance that such positive trends will continue or that there will not be any increases of new infections or new variants that may impede or reverse recovery and such positive trends. In response to the impact of COVID-19, we took a variety of actions in 2020 and to date in 2021 to ensure the continuity of our business and operations and to secure our liquidity position to provide financial flexibility. These actions include amending certain financial covenant ratios in the fourth quarter of 2020 through the third quarter of 2021, as may be needed due to the ongoing and uncertain future impact of the COVID-19 pandemic on our business and operations. We also furloughed team members beginning in the second quarter of 2020 and completed a workforce reduction plan in the fourth quarter of 2020 that impacted approximately 1,500 team members. As of March 31, 2021, 1,100 team members continue to be furloughed. Prior to re-opening our resorts and sales centers, we introduced the HGV Enhanced Care Guidelines, designed to provide owners, guests and team members with the highest level of cleaning protocols and safety standards recommended by the Center for Disease Control and Prevention and cleaning solutions approved by the Environmental Protection Agency in response to the COVID-19 pandemic. While we hope that conditions in the hospitality and travel industries continue to reflect the improvement that we saw during the March travel season, the pandemic continues to be unprecedented and rapidly changing, and has unknown duration and severity. Further, various state and local government officials may issue new or revised orders that are different than current ones under which we are operating. Accordingly, there remains significant uncertainty as to the degree of continuing impact and duration of the conditions stemming from the ongoing pandemic on our revenues, net income and other operating results, as well as our business and operations generally.
